Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an air-core coil winding insertion device for winding an air-core coil (high-frequency coil) used in an electric circuit of an electronic tuner and inserting the coil into a substrate. About.

[Conventional technology]

As described in Japanese Patent Application Laid-Open No. Sho 62-178000, a conventional air-core coil insertion device positions a coil wound in a predetermined shape in advance in a coil supply section, and chucks a coil lead from the left and right from this state. Inserted into the board.
A coil winding device generally winds a coil around a winding shaft and then drops it in a loose state on a chute installed below the winding shaft.These coils are positioned by a coil supply unit by some means and chucked. Inserted into the board.

[Problems to be solved by the invention]

In the above prior art, since the winding step and the insertion step of the air-core coil are separated, the wound coil is in a free state, so that a device for separating and aligning the loose coil is necessary, which is particularly flexible. Since the coil is easily entangled, there is a problem of reliability in separating and aligning. Also, no consideration is given to high-density insertion of coils and insertion of various types of coils, and there has been a problem that adjacent parts cannot be inserted due to interference between the chuck and a coil having a different lead pitch.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an air-core coil winding insertion device capable of improving the reliability of positioning of a wound coil, inserting a coil with high density, and inserting various types of coils.

[Means for solving the problem]

In order to achieve the above object, the air-core coil winding insertion device according to the present invention increases reliability by separating and aligning a coil wound with a coarse winding pitch or a flexible coil having a small wire diameter from a loose state. Considering that there is a very difficult situation, the coil lead is clamped and positioned when the wound coil is on the winding shaft, and then the coil is removed from the winding. The structure is such that the coil lead is re-chucked and inserted into the substrate, and the coil wound on the winding shaft is continuously positioned without inserting the coil into the substrate and inserted into the substrate. In addition, the coil lead is inserted into the substrate by a pair of chuck claws which slide from diagonally above, so that the coil can be inserted onto the substrate at a high density. Further, the above-mentioned pair of chuck claws are made into a unit so that a unit for each coil lead can be moved in the lead pitch direction. , And various kinds of coils can be wound and inserted.

[Action]

The above air core coil winding insertion device positions the wound coil on the winding shaft without separating it, then chucks the coil lead with the coil removed from the winding shaft and inserts it into the board This eliminates the need for separating and aligning the coil from its loose state, which simplifies the mechanism and eliminates factors such as entanglement between the coils and bending of the leads. Greatly improves reliability. In addition, since the coil lead is chucked from obliquely above when inserting the coil, there is no interference between the inserted coil on the substrate and the chuck claws, so that the coil can be inserted with high density. Further, by changing the pitch of the two sets of chuck claws and changing the diameter of, for example, four winding shafts, it is possible to cope with various kinds of coils and to wind and insert coils having different winding diameters and the number of turns. .

Next, as shown in FIG. 11, when the upper forming arrow 36 and the lower forming arrow 32 return to their original positions, the winding end lead 1b returns by the angle θ due to springback and coincides with the directional position of the winding start lead 1a. That is, the angle θ is the amount of springback, and varies depending on the number of turns of the coil 1 and the wire diameter. Therefore, if you know this springback amount in advance,
By replacing the rotation amount of the pulse motor 64 of the reel rotation drive unit I shown in FIG. 4 with the rotation amount and inputting it to the control unit, it is possible to deal with software without component replacement or adjustment. Moving each of the upper and lower forming arrows 36 and 32 by the dimension 1 in FIG. 10 relative to the winding shaft 22 by the pulse motor 35 of the winding lead forming portion B in FIG.

With the above configuration, when the cylinder 155 operates, the chuck claw 150 can be moved back and forth. As described above, the unit is formed as a unit with the components included in the chuck holder 134, and is provided to face each of the coil leads 1a and 1b.

Next, the operation of the insertion head section E will be described with reference to FIGS. 29 to 32. FIGS. 29 to 32 are explanatory views of the operation of inserting the coil of the insertion head portion E of FIGS. 18 to 28. First, the coil 1 gripped by the coil lead clamp jig H is sent to the position of the coil lead clamp jig H shown in FIG. One insertion head E is moved to a position directly above the coil lead clamp jig H by the XY positioning unit D. Then, the cylinder 155 of the insertion head E shown in FIG.
5, the leads 1a and 1b of the coil 1 gripped by the chuck claws 27 and 26 of the coil lead clamp jig H with the chuck claws 150 as shown in FIG. Next, the chuck claws 27 and 26 are opened by an opening / closing cam 81 'having the same shape as the opening / closing cam 81 operated by a cylinder (not shown). Next, after the entire insertion head is raised by the cylinder 114 of the insertion head portion E, the insertion head is moved to a predetermined position on the substrate 2 by the XY positioning unit D. Here, the insertion head of the insertion head portion E is again lowered by the cylinder 114, and the coil leads 1a and 1b are inserted into the predetermined holes 2a of the substrate 2 in the coil chuck state shown in FIG. 28 as shown in FIGS. 29 and 31. , 2b and stop.
Thereafter, the cylinder 155 is operated to retract the chuck pawl 150 as shown in FIGS. 30 and 32. Then cylinder 144
By operating (FIG. 19), the pusher 139 descends, and the side guide 140 also descends. As a result, the projection 149 (FIG. 19) of the side guide 140 hits the stop surface of the chuck holder 134 and stops at a fixed position. When the pusher 139 is further lowered, the coil 1 shown in FIGS. 30 and 32 is inserted to a fixed position. Switching of the insertion direction (XY direction with respect to the plane) to the substrate 2 is performed by the cylinder 122 (FIG. 19).
By rotating the shaft 177 through the rack 120. When the pitch between the coil leads 1a and 1b is different, the interval between the pair of chuck holders 134 is changed by operating the pulse motor 128 and rotating the cam 125. Thus, the distance between the pair of the chuck claws 150, the side guides 140, and the pushers 139 simultaneously changes.

According to the present embodiment, since the coil is positioned and transferred to the insertion head in a state of being on the winding shaft without freeing the wound coil, the coils are entangled with each other or the coils are oscillated by a vibration feeder or the like. The reliability of the supply of the coil is remarkably improved without causing dirt or bending of the coil lead portion due to friction of the coil. Also, it has a structure in which four winding jigs of the winding jig and two positioning portions each having a V-groove of the lead positioning portion can be switched by a coil. One of the insertion heads is also paired by a pulse motor. Can be continuously changed, so that at least two or more types of coils can be inserted continuously or alternately, which is very effective when several types of coils are inserted into one substrate. .
Further, regarding the coil insertion, since the lead is chucked, the side surface of the coil is guided, and the coil is pushed in by the pusher, the flexible coil can be inserted reliably.

〔The invention's effect〕

ADVANTAGE OF THE INVENTION According to this invention, since the coil which has been wound and positioned on the winding shaft without being separated is chucked and inserted into the substrate, the reliability can be greatly improved, and the coil lead can be obliquely moved upward. High-density insertion is possible because there is no interference with the already inserted coil, and winding is performed by changing the diameter of the winding shaft. There is an effect that can be inserted.
